Introduction Safe drinking-water is essential for healthy life, and United Nations (UN) General Assembly declared safe and clean drinking-water as a human right essential to the full enjoyment of life [1]. Moreover, the importance of water, sanitation and hygiene for health and development has been reflected in the outcomes of a series of international policy forums [1]. These have also included health and water-oriented conferences, but most importantly in the Millennium Development Goals (MDG)

The Mississippi River originates in Minnesota and winds it way down to the Gulf of Mexico. The Mississippi is iconic to American culture, and there is a fondness for the Old Man River; where images of paddleboats and Tom Sawyer come to mind. What does not come to mind is our nation’s river is sick. According to a report in the St. Louis Dispatch, the Mississippi is the second most polluted river in the United States, coming in just behind the Ohio River (Bernhard, 2012). The Mississippi is experiencing

impacted by this type of contamination. Toxic agents, in my example specifically tetrachloroethene (PCE), have many harmful effects on human health including affecting the central nervous system, causing cancers and causing pulmonary edema (Tetrachloroethylene Toxicity, 2017). This issue also effects the economy adversely. The cost to clean up groundwater contamination can vary wildly depending on the scope and severity of the contamination, but regardless of the cost it usually

Superfund Contamination In contemplating my topic to write about I was having a mild amount of difficulty, not too much but you could say I was confused. Then I heard a knock at the door, when I answered I was given a pamphlet that informed me of the contamination present in out water. One of the issues involved talked of superfund contamination clean up, this was new to me so to the internet I went. After researching Superfunds, I found that dangers to the environment are much closer to

INTRODUCTION Threat with chemicals is so serious that some routinely used chemicals may be mutagenic to human population (Saghir et al. 2001) suggesting the ever increasing risk of hazardous chemicals to human exposure. In recent times, our attention has been drawn to human-induced environmental changes and their potential threat to life through a growing number of chemical mutagens and their effects on the living system(Margarita Topashka-Ancheva and TsvetelinaGerasimova (2012). Pesticide Genotoxicityon

These strains of bacteria have the capacity to transform sugars to acetic acid directly without creating ethanol as an intermediate (Jia et al., 2007). The overall chemical reaction conducted by these bacteria may be represented as: C6H12O6 → 3CH3COOH. According to Jia et al., 2007 these acetogenic bacteria synthesize acetic acid from single-carbon mixtures, including methanol, carbon monoxide, or a blend of carbon dioxide and hydrogen: 2 CO2 + 4 H2 → CH3COOH + 2 H2O. It is also described in the

These were used as the standard mixtures. Carbon tetrachloride (CCl4), tetrachloroethylene, chlorobenzene, 1,1,2,2-tetrachloroethane, 1,2-dichloroethane, dichloromethane & Chloroform were sourced from Tianyi Chemical China. The stock solutions were diluted with pure water at different concentrations to prepare the working standard

Site background and history The Harbor Island site covers about 400 acres and is an industrial area in Seattle, Washington, at the mouth of the Duwamish River, close to Elliott Bay (see Figure 1). The island was created around 1905 from sediments coming from the Duwamish River. Since 1912, the island has been used for commercial and industrial activities, including secondary lead smelting, shipbuilding and repair, bulk petroleum fuel storage, metal fabrication, and containerized cargo shipping. There

Negligent companies who don’t care about the well being of individuals but themselves are harming the community in the most brutal way. Argo Motors and PG&E were the perfect examples of Tort Law and negligence because they cared more about making more profit off their companies and not the well being of people; leading to extreme measures such as hiding evidence and scheming on how to get away with it. In this analysis, I will talk about the Class Action and Erin Brockovich cases, two cases that
